IMPROVEMENT IN HAY-TEDDER-TEETH ATTACHMENTS.

Specication forming part of Letters Patent No. 198,410, dated December18, 1877 application filed September 18, 1877.

To all whom it may concern:

Be it known that I, JOHN MUDGETT, of South Tunbridge, of the county ofOrange, of the State of Vermont, have made a new and useful Improvementin Hay-Tedder-Teeth Attachments 5 and do hereby declare the same to bedescribed in the following specification and representedwin theaccompanying drawings, of which- Figure 1 is a front view, Fig. 2 a sideelevation, and Fig. 3 a longitudinal section, of a tooth-supporting armand appliances containing my invention, which consists, rst, in thecombination of a hooked spring with the toothcarrying arm and the twoteeth pivoted thereto, and provided with the bell-crank, arranged withand connecting them, as set forth; second, in the combination of curvedmetallic hinge-pieces with a wooden carrying-arm and the hooked springand the two teeth provided with the bell-crank, arranged with andconnecting them, as set forth.

In the drawings, the two tedder-teeth are shown at A A' as connected bya bell-crank, B, arranged with them, as set forth, all being in onepiece of material. These teeth, near their junctions with the crank, areconnected with the carrying arm or lever C by being pivoted thereto bymeans of two curved metallic bars or connection-pieces, D D, formed asshown, and fastened to opposite edges of the arm by screws or othermeans, the pivotal bearing of the arm being shown at a. There is alsofixed to the arm a spring, E, whose free end is provided with ashoulder, or is bent or hooked, as shown at b. This spring bears on themiddle part or wrist of the bell-crank B, and serves as an elasticsupport for the teeth. The hook is to prevent the crank-wrist from beingturned of the spring during backward movement of the prongs or teeth AA. The wrist of the bell-crank of the operative shaft of the tedder isto work in the pivotal bearing a, and the arm is to be operated thereby,and otherwise in the usual way.

When each tooth of a hay-tedder is controlled in its action by a spiralor helical spring at its heel, such tooth is very apt to get bent out ofits proper position relatively to the others of the tedder. With myimprovement or invention each tooth is not only firmly supported, butrendered stronger and less liable to derangement or working improperlyout of place, and it will operate to much better adlvantage.

I therefore claim as of my invention as follows:

l. The combination of the hooked spring E with the teeth-carrying arm orlever C and the two tedder-teeth A A', pivoted thereto, and providedwith the connecting bell-crank B, all being substantially as speciiied.

2. rIhe combination of the curved metallic hinge-pieces D D, the woodencarrying-arm C, the hooked spring E, and the two hay-tedder teeth A A',and their connecting bellcrank B, all being arranged substantially asset forth.

JOHN MUDGETT.
